Invasive Species

Bothriochloa pertusa is a perenial grass that has been introduced to many Caribean islands and Australia. It has established itself in many native savannah, shrubland and riparian biotas where it is able to out compete many native species due to its ability to establish new individuals via stolon growth. In these areas it establishes dense mats and shades out any slower establishing species. In Australia it is used as a stock feed due to its ability to establish in the poor dry soils of Northern Queensland.
